Hi Jeff,

Ping problem description:
After we moved up netxen adapter's firmware to 3.4.19, we saw this ping
problem on x/pBlade.  After configured interface up, ping -c 1
10.10.10.10 failed. Netxen adapter couldn't accept ARP broadcast packet
somehow. If I manually added MAC address in the ARP table, then ping
start working.

netxen adapter should finish initilization after system boot. But on
some platform, looks netxen adapter didn't initilization correctly after
system boot up, so have to re-load the firmware again in probe routine.
Also re-initilization netxen_config_0 and netxen_config_1 registers.

Let me know if you have any question for this patch.

Thanks
Wendy Xiong
